Extremely simple category on NSTimer which makes it able to use blocks.
I figure if you're using a block, you probably won't need to pass any userinfo object into the timer... you can get to whatever you need just from the block. So, I just hijack the +scheduledTimerWithTimeInterval:target:selector:userInfo:repeats: class method and it's brother -init..., setting it to use itself as the target, and to execute the class method +jdExecuteSimpleBlock: (which is part of the category) then pass the block you specify as the userInfo object which is then uses in the execute method. Pretty straightforward stuff.
Very simple:
[NSTimer scheduledTimerWithTimeInterval:2.0 block:^
{
[someObj doSomething];
[someOtherObj doSomethingElse];
// ... etc ...
} repeats:NO];
This may be overkill for most NSTimer operations... I mean, do you really have a need for a block? Couldn't you use the selector methods? Sure you could... but sometimes it's more elegant to use a block... so here you go.
